ABSTRACT:
A process for controlling the arc in plasma arc reactors having two electrodes in which reactor the reaction charge forms a reaction layer covering one of the electrodes and is a point of arc attachment. The reaction layer is characterized as non-conductive for a period of time causing an arc struck between the uncovered electrode and the reaction layer to short-circuit. An electrically conductive material is added to the reaction layer stabilizing the arc. Substantially pure molybdenum is prepared from molybdenum disulfide.
